Unhappy A/C just recharged - but no cold air?

Hi there. New poster, not too technical, sadly. I have a 1997 4.0 liter 6 Cyl Ranger Super Cab XLT automatic. 128K miles. I never did anything with the A/C since I got the truck years ago, as I assumed the compressor was out. Well, I did the old R134a recharge. At first, nothing was happening, and the AC clutch was not even engaging. But after running the engine about 20 minutes dispensing the coolant, then the AC clutch started cycleing. Sure enough, instead of blowing HOT air, it was almost COOL air, but nothing approaching COLD air. So, not sure where to even begin. Since the clutch was working again, I was kind of excited, but since it didn't even really even get cool after that, I am not sure if I have a bad compressor, or something else. Is there anyone who can shed some light for a novice Ranger owner. Thanks!

Gene

If the compressor is cycling on and off it prolly doesn't have enough of the R134. You can get one of those gauges and check it. I have one. Comes in handy from time to time. Had that problem with mine. If you decide and get another can of the stuff, I'd get the one with the stop leak. It fixed mine, and we have the exact same truck engine-wise.

Thanks very much Tom, I will check into getting a gauge. I emptied a 13 ounce can of coolant, but not sure how much is supposed to be added. So, if the A/C clutch is coming on, does that mean the compressor works?

If the system was fully drained, then I dont think one can would fill it. I just did mine 2 weeks ago and it took one of those big cans on R134 with stop leak and one of the smaller cans to get it going. Right now it's blowing ice cold and has been working great for about 2 weeks now which is the longest it's worked since i got the truck. If the Compressor is kicking on, I'd assume it works. Not to sure tho.

off topic question - if your name is Brad, why is your thread signed "Gene" ?

Thanks again Tom. You were right. I added to the 13 OZ can an additional 19 OZ can of Arctic Freeze http://4x4offroadtruckparts.com/n/ar...t-r-134a-13-oz

As soon as I had that can added, I checked the pressure and it shows to be in the lower end of the mid range, (green) so the pressure is acceptable, but another can would probably be good. But I will hold off for now to see what happens. It is now blowing very cold air, and I am really pleased to be able to have the AC working after all of these years. Wish I had tried this sooner. Thanks again.

Just keep an eye on it and see how long the charge holds. There really isn't much sense in adding another can if it's just going to leak out.

Smile Re: A/C just recharged - but no cold air?

I have a 1991 ranger XLT that keeps blowing the A/C orifice tube into the evaporator so far i cant reach it so i put in another, it worked great and pressures normal then one day i let it idle and normally my pressures increased prob to 350 then boom pushed a third on in, it blows 35 degrees at 100 rpm until this event happens.. can you please tell me why? how do i make it stop doing this? any info on this please assist. that's right i have 3 orifice tubes i my evap, no pressure problems, cold as an icebox and now it has yet sucked another into the evap. when this happens my lo side psi naturally goes up to 60 psi, proving there is refrigerant bypassing the tube and that it has pushed the tube in again. it fights nice and tight when I put the new on in so I don't have any idea how many I can put in there before it a series of orifice tubes. isn't there suppose to be a crimp or something to keep the tube in place?

check the orifice tube, it may have been blown into the evaporator, what are your pressures?

you prob have air in the system also, along with your dryer being old and full of moisture, heres what you do, drain, flush, change orific tube and ALL the "O" rings, change dryer, put in some synthetic pag oil, evacuate system for and hour, check for leaks watching the gauges for any drop in 15 minutes, if no drop recharge with R-134 w/ leak stop and oil in it.

usual 1.75 pounds of refrigerant is needed, get the kind with the synthetic oil and stop leak and has the new ice 32 refrigerant in the can
